Southwest Airlines is currently in the announced rollout phase for Starlink with zero aircraft equipped as of the latest data. Despite a high fleet coverage ratio of 86.2% reported, this figure likely reflects future projections rather than current installations. There are no confirmed Starlink observations on the TPA->MKE route, no recent news indicating active deployment, and no community sightings. Given the rollout status is 'rolling_out' but with zero equipped aircraft and no route-specific evidence, the probability remains anchored at 0.0. The fleet coverage ratio is not treated as a floor here because the rollout is not yet active (equipment count is zero), and the perplexity context confirms no current equipment. Therefore, the probability is conservatively set to zero with high confidence.
